Radio Shack CID 2903 Caller ID Box User Manual

Important Information
FCC INFORMATION
We have designed your CID to conform to
federal regulations, and you can connect it
to most telephone lines. However, each
CID (and each device, such as a
telephone or answering machine) that you
connect to the telephone line draws power
from the line. We refer to this power draw
as the device's ringer equivalence number
or REN. The REN is on the bottom of the
Caller ID.
If you use more than one telephone or
other device on the line, add up all of the
RENs. If the total is more than five (three
in rural areas), your telephone might not
ring. If ringer operation is impaired,
remove a device from the line.
Your CID complies with Part 68 of
FCC
Rules
. You must, upon request, provide
the FCC registration number and the REN
to your telephone company. Both
numbers are on the bottom of the CID.
Note:
You must not connect your CID to:
coin-operated systems
party-line systems
